Title: Improvements in or relating to methods of manufacturing two-sided mosaic plates for cathode ray tubes
IPC: H01B1/00
Filed: 1963-10-23
Abstract: 989,770. Cathode-ray tubes. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Oct. 23, 1963 [Oct. 26, 1962], No. 41856/63. Heading H1D. In a method of manufacturing two-sided mosaic plates for cathode-ray tubes, the plates comprising an aluminium oxide foundation provided with electrically conducting ducts extending from one side to the other and insulated from one another, the conducting ducts are formed in the natural pores of aluminium oxide produced by anodic oxidation of aluminium metal, the unoxidized metal and the non- porous oxide layer produced adjacent the metal being removed to leave a free porous layer, after which a conductive compound is chemically deposited in the pores. In a first embodiment, aluminium foil is first anodically oxidized using a solution of an organic carboxylic acid as the electrolyte producing a first oxide layer, then using a solution of sulphuric acid as the electrolyte which produces a second layer between the first layer and the foil with a thin non- porous layer being formed on the second oxide layer adjacent the metal. The first oxide layer adheres only weakly to the second layer and is removed mechanically and the pores are filled with conducting material to form the ducts. In a second embodiment, a film of aluminium oxide is first produced on an aluminium foil by anodic oxidation and the surface of the oxide film facing the foil is exposed by dissolving away the aluminium with a solvent until the pores extend right through the film. During this process the pores are filled with a substance which does not dissolve in the solvent in order to protect the oxide film from being dissolved, this substance being removed after the process and the pores filled with an electrically conducting compound. The mosaic plates are used in certain types of cathode-ray tube, for example image intensifying tubes, television camera tubes and image storage tubes.

Filed: 1971-09-08
Abstract: 1357943 Hairsetting apparatus BRISTOLMYERS CO 8 Sept 1971 [9 Sept 1970] 41885/71 Heading A4V A hair setter comprises means for heating rollers and means for spraying one or more selected rollers with atomized, dispensed or vaporized liquid. A roller 2 which has been heated is placed in a cup 5. As the roller is pressed, the cup 5 is pushed down tripping a pressure sensitive switch 7 which actuates a vacuum pump 6. The liquid is drawn from a reservoir 8 through a passage 5a to nozzles 9 from which the spray impinges on the roller. When the pressure on the roller is removed the cup 5 is returned to its normal position by a spring or other means. In a modification the roller is placed on a central post in the cup. The spray nozzles are directed downwardly or at an angle to the axis of the roller causing it to rotate on the post during spraying. The wall of the cup extends above the level of the casing of the chamber and the pump is activated by a downward pressure on the wall. In a further modification the cup is fixed and downward pressure on the support post as the roller is pushed on to it operates the switch for the spray mechanism. In another modification both the cup and post are fixed and the nozzles which are at two levels within the cup are supplied with liquid by a manually operated pump. The cup may form part of or be used with the apparatus in which the rollers are heated. Atomized liquid may be supplied from a chamber containing a pressurized liquid and a carrier gas.

Abstract: 1,061,977. Wafering hay &c. MASSEYFERGUSON Inc. Oct. 24, 1963 [Nov. 5, 1962], No. 41935/63. Heading A2B. In apparatus for making hay wafers by compressing hay through an annular series of die cells radially disposed in a vertical plane, the walls of each cell are movable by a fluid motor, the fluid motors operating the upper half of the cells being connected to a low pressure fluid source, and the motors operating the lower cells being connected to a high pressure fluid source. This reduces the cross section of the lower cells to compensate for their receiving a higher proportion of the hay, due to gravity. An automatic pressure responsive valve may be inserted between the high and low pressure fluid sources to maintain a fixed ratio between the two pressures and the ratio may be manually adjustable. Comminuted hay is fed by helix 58 and a pair of deflector vanes 60 into the wafering chamber 52, wherein a pair of rotating arms carry rollers 64 for pressing the hay against knives 68 which separate the radial die cells. Each die cell has a pair of movable walls 70, 72, hinged to the back of knives 68. The walls are moved hydraulically by piston-cylinder assemblies 80 to vary the cross-section of the die cell. The pipes 82 supplying hydraulic fluid to the upper half of the die cells are interconnected by manifold 84 to a low pressure supply 92, whilst the lower dies are actuated through separate manifold 86 and low pressure supply 90. The low and high pressure supply pipes are interconnected through automatic valve 98 which preserves a constant pressure ratio between the two.

The support member 1 has projections 2 spaced apart along its length such that each projection is positioned between two adjacent articles in a row, Fig. 1. The member 1 may be a rectangular frame, Fig. 3a, or may take alternative planar forms, Figs. 3b-3e (not shown), and may be of plastics or a light metal. The film 3, initially wider than the length of a row of cans, is wrapped around the cans in a direction perpendicular to the rows, and its ends are heat-sealed together, whilst both side edges of the film, corresponding to the ends of the rows of cans, are left free to provide openings 5, 5<SP>1</SP>. The whole package is now heated to shrink the film 3 about the cans. The openings 5, 5<SP>1</SP> enable the package to be carried, using one end of the member 1 as a handgrip, the cans being supported by the projections 2. The package may have an opening at one end only, and projections may be provided only between every other can, or on only one side of the support member, instead of between each pair of cans as shown. In use, pairs of cans may be severed from the package leaving the remainder still firmly held.

Filed: 1977-10-12
Abstract: 1534378 Adaptive array; communications system MOTOROLA Inc 12 Oct 1977 [22 Nov 1976] 42485/77 Headings H4A and H4L The invention relates to an FM communications system using null steering adaptive array receiving apparatus wherein automatically forming the reception lobe of a plurality of antennae on an A/C 10, Fig. 1, with a null in the direction of a jammer A/C 12 and a maximum in the direction of the communicating A/C 11, is characterized by the friendly A/C transmitting an FM communication signal together with a relatively low level identifier signal substantially in-phase with the FM carrier, the FM modulating signal being periodically blanked for a relatively short period so that only the carrier signal modulated with the identifier signal is transmitted during the blanking periods. At A/C 10, Fig. 2, for each antenna 20, 21, 22, 23, the identifier signal is separated (45) from the desired FM signal and utilized to produce the reference signal (47) at the same frequency and phase as the carrier signal, which reference signal is utilized, only during the time the FM signal is periodically blanked, to retroactively adjust the amplitude and phase of signals from the antenna so that the maximum is formed in the lobe. The null is formed between the blanking periods, the relative power of the carrier being spread out by the modulation to below the level attracting the nulling action. An integration, storage stage (31, 36) maintain the null and maximum during the time between the blanking periods. The identifier signal may be a secure PN code, constantly changing and not predictable, thus making it impossible for anyone transmitting a jamming signal to place the correct identifier on his signal. The signal from each antenna is split into quadrature components whicn are so amplitude weighted (32, 37) that the output of a summer 40, receiving all the weighted quadrature pairs equals the reference signal for the maximum (or zero for the interference null). The weightings are produced by a correlator/mixer/multiplier 30, 35.
